4.6 Headphone Select
The Headphone outputs on your Quantum-series interface feature
independent DACs. For Quantum users, the source for both
headphone outputs can be selected from any output pair. By default,
both headphone outputs mirror the Main Left/Right mix.
For Quantum 2 users, UC Surface allows you to select the “B” source
from any output pair. The “A” source always mirrors outputs 1/2
4.7 MIDI Control
As previously mentioned, the preamps on your Quantum-
series interface can be controlled via MIDI over Thunderbolt. This
feature can be enabled and disabled from UC Surface.
The preamp functions on your Quantum-series interface can be controlled via
MIDI from your DAW application, an external MIDI controller, both, or neither.
Select ‘Internal MIDI Only’ if you only want your DAW to send and receive MIDI
information to and from the preamp controls. Select ‘External MIDI Only’ if you would
like to control your preamp functions from a MIDI device that is connected to the
MIDI connections on the back of your Quantum-series interface. Select ‘Enabled’
to use both. Select ‘Disabled’ if you only want local control of your preamps.
Note: Even when MIDI control is disabled, you can still control your preamp functions
from UC Surface and Studio One.
See Section 3.3 for the Quantum preamp MIDI mappings.
